Analysis of causes of transverse cracks in tundish working lining
The tundish is an important intermediate equipment that connects steelmaking and continuous casting in the steelmaking production process. It can store molten steel, distribute molten steel, ensure continuous pouring, reduce pressure and stabilize flow, promote the floating and removal of non-metallic inclusions, and uniform molten steel composition and temperature. And many other metallurgical functions. The normal operation of the tundish directly affects the antegrade of the continuous casting process and the final quality of the slab. However, due to the particularity of the working conditions of the tundish, not only the high-temperature molten metal is constantly eroded, but also experienced a sudden drop in temperature, which has a great impact on the life of the tundish. Cause Analysis 1.The difference in the composition of different dry ingredients The two dry aggregates use different grades of sintered magnesia or fused magnesia. When baking at low temper...
